Holiday air travelers could be going nowhere fast, with already long lines at airport security checkpoints getting even worse as the season kicks off today, according to federal statistics.

Checkpoints at Fort Lauderdale International Airport, Los Angeles International, and Dulles and Reagan airports in Washington, D.C., garnered eight of the top 10 spots nationwide for the longest wait times. The worst screening area in the country was Fort Lauderdale’s Checkpoint D with a maximum wait time clocked at a staggering 63 minutes. In another instance, the same checkpoint logged a 60-minute wait.

The Transportation Security Administration started posting security-delay wait times on its Web site last summer for travelers to use when planning flights.

The TSA has been requiring passengers since September to remove coats and sweaters during screenings. In the wake of terror bombings that downed two jetliners in Russia last summer, there’s been increased concern that the heavy clothing might conceal weapons or explosives. “We’ve had great success keeping wait times down to 20 minutes,” said TSA spokeswoman Ann Davis. “There are certain anomalies that sometimes depend on how many planes leave a terminal at any given time.”

The data, compiled by the TSA and first reported in Tuesday’s Wall Street Journal, is based on wait times between Oct. 12 and Nov. 9.

Trying to keep passengers moving through checkpoints comes as a travel survey reveals millions of Thanksgiving travelers will leave their homes starting today in what is expected to be the busiest holiday exodus since before 9/11. The American Automobile Association said 37.2 million travelers are expected use the skies, rails and roads to embark on the annual turkey-holiday trek – an increase of 3 percent compared to last year.

Some 4.6 million people will travel by plane, with the Port Authority expecting 1.5 million travelers to use Kennedy, La Guardia and Newark airports – an 18 percent increase over last year. AAA also projects that 30.6 million people will travel by car with another 2 million travelers expected to board a bus or train.

The increased travel comes as average gas prices nationwide have reached $1.94 a gallon – up 44 cents from a year ago.

New Yorkers can expect a combination of mild and chilly weather over the holiday weekend. AccuWeather predicts temperatures will reach 64 tomorrow with a chance of morning rain.
